Product Introduction
UK Alphasense Air Quality Sensor VOC SensorVOC-A4 Description:
VOC-A4Can detect both VOC gas and CO gas.
Using VOC-A4 and CO-A4 sensors together allows estimation of VOC concentration without bias.
Alphasense VOC electrochemical sensors VOC-A4 and VOC-B4 are the perfect partners for our amperometric four-electrode air quality sensors. In ambient air quality applications, VOC-A4 and VOC-B4 should be used in conjunction with one of our A-series (CO-A4) or B-series (CO-B4) carbon monoxide sensors. Although we recommend no bias voltage for these sensors in air quality applications, the bias of both VOC-A4 and VOC-B4 can be changed to 0V, 0.1V, 0.2V, or 0.3V, allowing selection of different gas detection.
